蒸发冷却式直膨空调在地铁车站冷源系统中的应用

Application of evaporative cooling direct expansionair-conditioning to cold source system of subway station

北方地区某地铁站工程存在地面冷却塔布置困难、地下机房用地紧张等问题,从技术性和经济性两方面对蒸发冷却式直膨空调在地铁车站冷源系统中的应用进行分析.结果表明,与蒸发冷却式冷水机组相比,蒸发冷却式直膨空调在地铁车站冷源系统的应用上更具优势,不仅可以减少机房面积及土建投资,还能节省设备初投资和运行维护费用,同时运营也变得更简单.

There are some lssues in one north subway station project,such as layout difficulty of cooling tower on the ground,intensity in utilization of land for underground data room,etc. The application of evaporative cooling direct expansion air-conditioning to cold source system of subway station is analyzed in the respects of technology and economic. The results show that the application of evaporative cooling direct expansion air-conditioning to cold source system of subway station has more benefits than the evaporative cooling water chiller,it can not only reduce the area of data room and the investment of building construction,but also reduce the initial investment of equipments and operation & maintenance cost,which makes it easier to operate.
